  • FIG. 12 is finally a detailed view in longitudinal section on the axis XII--XII' in FIG. 11.
  • This casing 1 is advantageously made of molded plastics material withstanding the conditions of use, for example of polyphenylene oxide.
  • This casing 1 essentially comprises two separate parts, namely a lid 2 and a container 3 which are articulated together on the side by hinges 4, and the closing movement of which is assisted by a ram 5 (FIG. 3).
  • this machine comprises firstly a hinged lid 10 intended for the insertion into a cradle 12 of the spool 11 of negative film to be developed.
  • the end of the film given the general reference F is introduced between a pair of engagement rollers 13, 14 operated manually from the outside or automatically.
  • the film F is then taken over by a pair of motorized rollers 15, 16.
  • a cutter 17 (see FIG. 4)disposed before the two pairs of rollers 13, 14 and 15, 16 cuts the end of the film F when the latter has been completely unwound.
  • the film F pulled by motorized rollers 21, 22 penetrates into the film development section H of the film development unit A in the container 3 shown in detail in FIGS. 2, 4 and 5.
  • This film development section given the general reference H, consists in known manner of a plurality of successive tanks 23 to 27 and is followed by a drying section 28.
  • Each tank 23 to 27 is filled with suitable liquid chemical products, for example type "C41", heated by electrical resistors 29 to the desired temperature.
  • These tanks are, in order:
  • the clean washing liquid is fed into the second tank 27 and by way of an overflow passes into the first tank 26, thus always ensuring perfect counterflow washing.
  • the developed film F' then penetrates into the drying zone 28, wherein is subjected to the action of a heater fan 29 (see FIG. 4).
  • the dried developed film F' passes out vertically from the film development unit A through a slot, then penetrating directly into the exposure section C of the paper printing unit B disposed in the dark just above the film development section H.
  • the film F (see FIGS. 8, 9, 10) is guided between two parallel rails 31 and 32 provided with respective grooves 33, 34 disposed face to face in the same plane and spaced apart by a distance equal to the width of the film F to be developed.
  • the whole arrangement is driven by a single motor (not shown) and by sets of transmission means.
  • One of the two rollers, the roller 36 in the present case, has at each of its two ends an 0-ring seal 100 which grips the film F against the edges of the other roller 35, outside the exposed zone of the film. This 0-ring 100 ensures constant, regular and uniform pressure and is easily replaced.
  • the continuously advancing film F' In order to permit exposure of the dried developed film F' in the exposure section C (see FIG. 10), it is necessary for the continuously advancing film F' to be stored temporarily during the exposure phase.
  • the two guide rails 31, 32 are interrupted, at least on one side, to form two bends 39, 40, thus defining between them a loop-shaped accumulation zone 41, taking advantage of the flexibility of the film F'.
  • the film is driven continuously, whereas the frame being exposed is stationary, so that it forms a stored loop 41 through the driving action of the last pair of rollers (90,91) of the developing unit H , while for the exposure the others pairs 57, 58, 59 and 66 are halted.
  • the dried developed film F' which advances vertically from the slot 30, then penetrates into the negative carrier of the exposure section C, thence passes out again through the slot 41 provided for the purpose in the top of the casing 1, more precisely in the lid 2 (FIG. 1).
  • the exposure section C of the paper printing and development unit B is disposed in the dark substantially above the film development unit A.
  • This exposure section C comprises essentially, in order (see FIGS. 4, 11 and 12):
  • a densitometer 42 access to which can be gained via a slot 43;
  • an exposure lamp 44 for example of the 75 Watt halogen type with elliptical reflector
  • the reference 53 designates the frame of the film F' which is to be reproduced, positioned in the negative carrier of the exposure section C.
  • This negative carrier system (see FIGS. 4 and 12) comprises essentially three pairs of motorized pressure rollers driven synchronously and controlled by the electronic board 81, namely respectively:
  • the reference 60 designates the optical axis for the exposure of the negative film 53 which is to be reproduced.
  • the light beam coming from the lens 52 encounters in a straight line a first mirror 61 inclined at an angle of 45° in relation to said optical axis 60.
  • This mirror 61 is also disposed above the film development section H. In order to facilitate understanding, this mirror 61 is schematically shown in FIG. 12 in an exaggerated position. It will however easily be realized that this mirror 61 must be disposed in the positions shown in FIGS. 2 and 11.
  • This mirror 61 is of a known type. It is in particular an optical mirror, that is to say one having an external reflecting face covered with a coating of tin. In an improved version this mirror 61 may be slightly adjustable in respect of its inclination in order to permit better optical centering.
  • the optical beam 62 reflected by the first mirror 61 is received by a second mirror 63, which is parallel to the first but disposed above the development section G of the printing unit B, this section being shown in detail in FIG. 6.
  • This second mirror 63 is fixed, but is preadjusted in accordance with the selected enlargement size.
  • the image 64 to be reproduced, reflected by the second mirror 63, is received on the exposure surface 65 of the feed section D of the unit B.
  • the film development unit A and the development section G of the paper unit B are disposed side by side in the container 2, so that some of the chemical treatment tanks and also the drying zones lie side by side but are in separate compartments.
  • the feed section D of the unit B contains in known manner a cassette 70 intended to receive the roll 71 of photosensitive paper P.
  • This paper P is driven by a pair of motorized rollers 72, 73 and is then applied against the exposure surface 65 by a fan 74.
  • a cutter 75 cuts the appropriate length of exposed paper P'.
  • a tank 76 intended to hold the developer.
  • a tank 77 intended to hold the liquid bleaching and fixing composition.
  • the first washing tank 26 of the film development section and the second washing tank of the paper development section G are one and the same.
  • the drying section 28 is common to these two sections H and G.
  • the tanks 23 to 27 receive a single rack, in which the film F to be developed progressively advances, while in the paper development section G the tanks 76, 77 receive two separate racks, whereas the other successive tanks 78, 26, 79 each receive one rack.
  • the tanks are each filled with an appropriate chemical composition depending on the treatment required, such as for example a composition C 41 for the section H or a so-called “fast” type chemical "Kodak "RA 4 " for the section G.
  • the developed photographic print E is received through the action of gravity in a reception tank 80 provided for the purpose at the front of the casing 1.
  • An electronic control board 81 automatically controls all the components of the machine.
  • the machine according to the invention offers numerous advantages over the machines listed in the preamble, particularly the machine described in American Patent US-A-4 185 912. Mention may be made of:
  • This machine can thus be used successfully for the integrated automatic development of photographic prints from negative films.
